l a Y (ci. zia-11) This inventionrelates to certain new and use- 4 ful improvements in nursing units for infants.

eifective-means for preventing inward displacement of the nipple relative to the bottle.

ing-fashion, as shown in F'igure 2, and to be encaged and effectually wedged in place by the" overlying portion of the cap to center the same on the bottle and to resist the inward transverse displacement of thenipple-fiange during feeding. As a further guard against such inward displacement of the nipple during feeding, the opposing top andbottom faces of the nipple-ange and top wall of the cap are provided with complementary interengaging elements preferably in the form of an annular channel or groove il and an annular rib Il, respectively. The groove in the nipple flange is disposed between its periphery and t-he base of the conoidal portion of the nipple and in Other featuresof the invention residein the construction and arrangement of parts hereinafter described and particularlypointed out in the appended claims.

In the accompanying drawing:

Figure lis a side elevation of my'improved nursing unit. Figure 2 is an enlarged fragmen- 'V tary vertical section thereof taken on line 2--2,v Figure 1. Figure 3 is a similar section taken on line 3 3, Figure 1. Figure 4 is a top plan view of the unit, partly in section. Figure 5 is a bottom plan view ofthe nipple.

Similar characters of reference indicate corresponding partsthroughout the several views.

This improved nursing unit, which has been primarily designed to meet the sanitary features of the wide-mouthed bottle and the' features of the natural or breast type of nipple consists of a food cell or body Il having a substantially cylindrical bottom portion and a remaining portion of frusto-conical form providing straight sides tapering slightly toward the bottle axis and' extending to the open mouth of the bottle. At its upper end the bottle is provided with threadfforming ribs Il with which the mating portionsof a detachable cap" or cover i2 are engageable for removably securing thenipple i3 in place on the bottle. The nipple is provided at its lower end the plane of thebottle, so that when the cap I 2 is screwed home the nipple is eiectually clamped against inward displacement.

Projecting outwardly from the nipple ange Il is a radial tab or finger piece I9 for facilitating the ready and convenient application and removal of the nipple to and from the bottle. The

nipple-retaining cap I2 has a notch or opening 2l in its side' with which the nipple-tab registers -and through'which it normally projects in. the

operative position of the parts. Disposed in the bottom face of the nipple-danse i4, and in register with and extending radially of the tab i9 is a venting groove or channel 2| which" bridges or spans the top edge of the bottle to provide a resulting air r.: communicating at one end with the interior of the bottle and at its other end through the cap-notch 2li with the atmosphere.

. As shown in Figure 5, the rim It of the nipple flange il is cut away substantially in the plane of the tab il so as notto obstruct the venti-ng Y -channel 2i.

I claim as my invention: e

1. A nursing unit, comprising a bottle having a cap detachably mounted thereon and containing an opening centrally thereof and a notch onv its side. and a nipple adapted to extend through 4said cap-opening and having a base-flange for disposition between the top edge of the bottle and the cap and having a tab projecting therefrom with an' outwardly twins base VHanse Il while 45 roiregistration witii said cap-notch. said nipplethecap l2 is provided in its top with alcenmi opening is through which the nipple rroiects ond-whereby the base -ilange of the nipple.

is clamped ilatwise between the top edge of the ange having a -retaining rim at its periphery adapted to'extend about the outer portion of the top edge of the bottle and being cut away in the plane of said tab, the latter having a ventina bottle and the opposing underside of the cap channel on its bottom side adapted to span the surrounding its opening. At its-peripheral edge this' nipple-danse has an annular-depending retaining rim I8 of substantially V-shaped cross section which is adapted to extend over the outer top edge of the bottle.

2. A nipple for nursing bbttles, comprising a body having abase flange for flatwise engagement with the-top edge of the bottle and having P01110!! 0f the 'SOP edle of the bottle in overhang- 56 a ,tab projecting therefrom in the plane thereof.
